Research Interests

Our laboratory has been involved in developing small animal models (rodent) for HIV research. The specificity of HIV-1 for human cells precludes virus infection in most mammalian species and limits the utility of small animal models for the studies of disease pathogenesis, therapy and vaccine development. To this end, a humanized mouse with long-term reconstitution of human functional lymphoid tissues was recently achieved by transplanting human hematopoietic stem cells into immunodeficient mice.

My research interests are to utilize the humanized mouse model to study:

  1. HIV vaccine strategies to induce protective immune responses and
  2. Immune-based therapeutics to enhance HIV immune responses

Critical evaluation of these various therapeutic approaches for the prevention of HIV infection is essential. The humanized mouse model offers a unique environment to test these approaches and provide a proof-of concept for human use. Visit the Translational Mouse Model Core Facility.
